SWITZERLAND • The full-service provider offering pre-media, digital printing, laminating, and pouch making services will install an ebeam Core 100/760 EB curing unit, mounted on a Grafisk Maskinfabrik GM EB30 coating line at its Madison, Wisconsin, USA, site in Q3, 2018.

This configuration will enable ePac flexible packaging to achieve instantaneous curing and a high-performance finish to overprint varnish (OPV) onto surface web printed materials from an HP Indigo 20000 Digital press.


The GM EB30 with an integrated ebeam Core 100/760 is optimized for OPV curing of material printed on an HP Indigo 20000 and delivers numerous competitive advantages to HP Indigo digital press users. Instantaneous ebeam curing of OPV means that lamination, with its lengthy drying times to ensure bonding, can be eliminated from the finishing stage. With ebeam, ePac will be able to send fully-cured, OPV coated material directly onto the next stage of production. In addition, ebeam curing produces a high-performance finish with an outstanding look and feel. High-gloss, matte and soft-touch finishes that are scratch, tear, puncture and fade resistant, result in substantially increased package and label durability and abrasion resistance. Protection of printed graphics is improved, providing increased heat resistance to reduce damage during heat-sealing or when adding zippers.

The new solution will also enable ePac to realize additional market opportunities by opening up a route to indirect food contact packaging. With ebeam-curable OPVs from GM, there are no photoinitiators, thereby providing an FDA approved solution for personalized indirect food contact packaging applications. Also important is the low energy nature of the ebeam curing process which, combined with a lack of chemicals such as photoinitiators, increases sustainability whilst lowering production costs.
